To all whom it may ooncem: v

j Be it known that we, Josnret Esonsn, residing at Pittsbur h, in the county oiv Alle ghenyand State 0 Pennsylvania, and J our? Nnsr, residing at W'cst ion", in the county and State of Pennsylvania,

Our invention relates to improvements in die-holders such as are employed in various implements and machines for printing and stamping signs-and characters, legible, mtelligible, decorative, or otherwise, upon suitable surfaces.

The invention is illustrated. in the accompanying drawings, of which- Figure 1 shovvs in perspective a die-holder such as is employed in a stamping machine, or for use by hand, equipped-with dies, and embodying our present invention; Fig. 2 is a View of this same die-holder With its dies in place, shown in vertical section; and Fig. 3 is a view in transverse section, the plane or section being indicated by the line LIL-III,

The die holder of the said patent-is provided with a lock orthei dies when inplace in the holder, such'lock being operative to alternately secure and release the-entire row ofdies simultimeously.

of dies arranged in straight-line forme- Petented leh. e, Twit.

Our present invention, though not necessarily so specifically limited, finds peculiar applicability in die-holders designed and intended to carry a. rev: of dies arranged in a formation which is not a straight-line ion mation; as, for example, a row oi? dies erranged in curved formation in horizontal.

plane, for'stainping a. succession of chemo-- tors in curved line upon a plane surface; 01', again, a row of dies arranged in curved ton motion in vertical plane, for stamping a succession of characters upon a. rounded surface. Figs. 1-3 of the drawings show the former arrangement, Figs. einnd 5 the letter.

Referring first to Figs. 1%, the die-holder is indicated at 1; it is provided with a dieseat' 2 whichyas best, shown in Fig. 3, is curvilin'eer when viewed in transverse section, and is adapted to receive a succession of dies,-df, d, d, etc, identical in. shape of body, severally removable and interchange "able, and adapted when assembled and epplied to enter and fill the die-sent. Each die is provided with a notch, n, adapted to re ceive the locking means. The lock consists 'of a member 3, formed conveniently as :1 leaf spring with an intnrned die-engaging end 4., and secured at its opposite end to the body of the die-holder, all as shown in Figs. 1 and 2. Normally this lofck stands in the position shown in Fig. 2, its diecngrging end protruding from the Wall of the die-seat and (when the dies are in place) entering the notches 'n in the bodies of the dies and so securing them in place.

A bolt 5 which extends through the body of the die-holder is normally held by the spring 6 in the position shown in Fig. 2,

with, one end adjacent the inner face of lock ing member 3. at a point remote from the point at, which member 3 is secured to the die-holder and the other end extending beyond the face of the holder. The protruding end of bolt 5 may be pressed inward (that is, to the right, Fig. 2) against the tension of spring 6, and in such movement the member 3 is en aged and forced outwnrd to the right .In that movement the die-engaging end 4 of member 3 is withdrawn from die-engeging position, into the well of the die-seat, and the die-sent is left free and unobstructed for removal, or change, and insertion of dies. When knob 6 is released from inward pressure, spring 6 carries it again to the position shown in Fig. '2, and the locking member, thus released, resumes again its normal die-engaging position. Fig. 2 shows bolt 5 riveted to member 3, and manifestly in such particular construction the resilience of spring 6' may be relied on, not onlyto shift the bolt, but also to bring or assist in bringing memberhl back to locking position.

From the foregoing explanation it will be manifest that, if desired, the locking member may be repressed and the die-seat left entirely unobstructed while the dies are being moved, and so the lock may be guarded from harm consequent upon oft-repeated blows from entering dies; and, on the other hand, it will be manifest that, by a proper shaping of contacting surfaces, the locking member, while securely holding the dies against accidental, withdrawal, may be made to recede in response to pressure from the entering dies to allow the dies to come to their place, whereupon it will spring forward to enter notches n and securethe dies. This end maybe attained by forming lock and die with the com lementary inclined faces a and 7) shown in ig. 6.

As shown in Fig. 3 the die-engaging portion 4 of the lock is curvilinear, corresponding in this respect to the shape of the dieseat and to the formation of the row of seated dies; and it will further be observed that the die-engaging portion is preferably formed as a succession of prongs, corresponding in number and spacing to the dies which the holder is designed and intended to carry.

Referring now to Figs. 4 and 5, it will be ,noted at a glance that the row of dies is 40' sectionythat, as before, the dies d are in all curved when viewed in vertical elevation or respects (except of course in their stamping faces) identical and are freely interchangeable. To this end the die-seat 2 may be regarded as a plurality of individual dieseats, arranged in radial grouping and of such depth as to bring the faces of the in- .serted dies to the desired relative positions and the locking notches in the dies to position for engagement by the lock. The die engaging end of the member 3 is correspondingly arc-shaped. Manife'stly, the holder of Figs. 4 and 5, when equipped with dies is adapted to stamp a rounded surface, in this instance a concave surface.

\Ve have in the foregoing description explained that our invention is peculiarly applicable to a die-holder for a row of dies arranged otherwise than in straight-line for- ,mation; we have described it as applied to line configuration, even though the lines he not, precisely speaking, curves.

\Ve claim as our invention:

1, In a die holder provision for seating and carrying. a plurality of dies, and a spring-impelled latch. capable of movement to protrude from and recede within the walls of said die-seat, said latch including a succession of prongs corresponding in number to the number of dies which the said die-seat is adapted simultaneously to receive.

2. In a die-holder rovision for seating and carrying a pluralit of dies in curvilinear arrangement, am? a spring-impelled latch capable of movement to rotrude from and recede within the walls of said die-seat, said latch including a succession of prongs corresponding in number to the number of dies which the said die-seat is "adapted simultaneoufily to receive, said succewion of prongs arranged in a curved line corresponding to the curvilinear arrangement of the seated dies.

3. In a die-holder rovision for seating and carrying a pluralit of dies in curvilinear -arrangement, and a spring impelled latch capable of movement to'protrude from and recede within the walls of the die-seat,
